Too/ll whom it may concern.-

Be it known that I, STEWART WELLS J AME- son, a citizen of the UnitedStates, residingat Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements inFountain-Pens; and I do hereby declare the following to be a full,clear, and exact descri tion of the invention, such as will enable 0ters skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon,'which form a part ,of this specification.

This invention relates to new and useful improvements in fountainensespecially adapted for drawin an comprises a threaded plug for attacment to the font of a penholder and also comprising pivotal points orpens which are hinged on a shou dered portion of the plug and on oposite sides of a central projection thereof an through which ink is fedto the adjacent faces of the pivotal ens. P The invention consists invarious details of construction and in combinations and arrangements ofarts, which will be hereinafter full describe and then specificallydefined in t e appended claims.

1 illustrate my invention in the accompanying drawings, in which Figure1 is a side elevation through my fountain drawin on. Fig. 2 is avertical sectional view. 1g. 3 is an enlarged detail view, in sideelevation, of one of the steel blades or pens. 4 is an edge view of theblades or pens; and i 5 is an enlarged view in elevation of the pl g,showing the projection havin an elongated aperture therein through whicink passes to the points of the ens. p Reference now being had to thedetails of the drawings by letter, A designates the font of thefountain-pen, and in the open end thereof a threaded plug B is adaptedto be fastened in the manner shown in thedrawings. B designates ashoulder upon said plug and serves as a stop to limit the distance atwhich the plug may be screwed in said font and the circumference of saidshoulder is milled, whereby the plug may be easily adjusted in place inthe ont. Projecting from the outer end of the In is an ink feeding anddistributing mom e15), having an elongated slot D therein, and uponopposite edges of said member are shou ders d, thus font, a threadedleaving a space through which the ink may pass longitudinally along theedges of said member to be fed to the pivotal blades E, forming the pensEach of said blades E is slightly curved longitudinal] and the inner end0 each is pivoted at to a shoulder formed u on said plug, one blade u oneither side of t e longitudinal opening in the pl'tijfiCblOll of saidplu desilgpates a hollow open-ended shell having 1; eads upon its innercircumference near one end thereof, and one end is tapering, as at F",and terminates in a flan e H. Said shell is designed to fit over the treaded circumference of said in and when screwed on the lug toward t e soulder B the flange H, at t e outer end thereof, is designed to contactwith the outer faces of each blade for the purpose of bringin the sametoward each otherin adjusting t e oints for drawing different widthsoflines. he blades E being of a resilient material willyield as theflange at the contracted end of said shell bears against the outer facesthereof and me be thrown to- Ward each other, and as the s ell isunscrewed the points will resume their normal position. From theforegoin it will be noted that a simple and eificient ountaindrawing-pen is afforded whereby the points may be easily and quicklyadjusted by the simple manipulation of the shell and affording a penwhich may be continually used without reloading r the same, which isusual withfountain-pens commonly in use.

Havin thus fully described my invention, what I e aim as new, and desireto secure by Letters Patent is- 1. A fountam drawing-pen, comprisin aplug portion fitted wit iin the same, and having a projection at one endwhich is provided with an elongated open: ing, blades ivotally mountedupon said plug portion, an a threaded shell fitted over said plug andada ed to frictionally on age the outer ed as c said hladeaas set fort2. A ountain drawing-pen, comprising a font, a threaded lug portionfitted therein and provided wit a projection having an elozi ated slottherein, resilient blades pivotal y mounted,,one oneach side of saidopen- 7 ing, and a shell having a threaded circumferonce adapted to fitover said lug and to frictionally bear against said b ades, as setforth.

3. A fountain drawing-pen, comprising a font, a plug having a threadedcircumference IIO fitted within said font, a milled shoulder upon thecircumference, a projection at one end of said plug having an elongatedopening, shoulders formed upon the opposite edges of said projection,the op osite edges of said rojection intermediate t e shoulders and endthereof being recessed to form an exit-passage for ink, resilient bladespivotally mounted upon said plug opposite to each other and adjacent tothe o enings in said projection, and a shell fitte over the plug andblades, and adapted to force the latter toward each other, as set forth.

4. A fountain drawing-pen, comprising a font and a threaded plug portionfitted therein, a projection at one end of said plug and having anelongated opening therein, pivotal resilient blades mounted upon saidplu one upon each side of said projection, a shel having threads uponits inner circumference and adapted to fit over the threads of said plugand provided with a contracted end, and a flange about the innermarginal portion of said contracted end, designed to bear against saidblades to force the same together, as set forth.

In testimony whereof I hereunto aflix my signature in the resence of twowitnesses.
